King Part # MB557SI-20

 Bearing buyers: To get the best possible deal on bearings- We suggest ordering at least four sets of bearings at one time. When going through check out, the shipping calculator will charge priority mail freight based on weight. Go ahead and place your order regardless of the shipping cost. (excluding the use of priority express) Once we see the order, we will determine the lowest possible cost to ship all the sets together, then we will adjust your shipping cost down and refund the difference. Keep in mind, this only works when you order at least 4 sets of bearings. Orders for less than four sets, (rods or mains) will not qualify for any freight discounts. We will clear out all remaining SBC bearings this way until they are all gone. To give you an idea as to what it would cost to send between 4-10 sets or bearings- expect to pay around 15.00 or around there. We've lowered the price of these bearings as low as possible, the best way to save further is to order as many sets as you can for the best possible combined shipping value. This offer applies only to bearings we have in stock. You can also message us for a shipping quote starting with at least 4 sets.
